SHUTTLE ATTACHMENT.

Application filed March 17, 1925.

To all whom it may cancer-a:

Be it known that l, 'llrrsonoan J. Gnnisro, 'a'citizen of'the United States, and a resident of Allentown, in the countyof Lehi-gh and State of Pennsylvania, have invented a new and ImprovedShuttle Attachment, of which-the following is-a full, clear, and exact description.

This invention relates to shuttle attachments and has articular reference to a shuttle and threat-cutting attachment of the character disclosed. in United States Letters Patent granted to me December 20, 1910, No. 979,282.

The attachment forming a part-of the shuttle disclosed in the above patent is practical to all its intents and purposes,but is susceptible to improvementfor controlling the movement of the thread to sever the thread to stop the loom if the thread is imperfect or deformed because of the fact that it is knotted or otherwise enlarged in cross-sectional size greater than a uniform size.

The device of the present invention has been tested and found to be efficient and effectual in carrying out the result aforementioned.

Another object of the invention is to produce a device which may be readily attached for use as a part of a shuttle, which tensions the thread as it is fed from the bobbin of the shuttle, controls the movement of the thread, and severs the thread in the event of a deformity on the thread.

With the foregoing, other objects of the invention will appear from the embodiment of the invention, which, by way of example, is described in the following specification and illustrated in the accompanying drawing, in which:

Figure 1 is a perspective view of the attachment of the present invention;

Fig. 2 is a plan view of a portion of a shuttle and bobbin mounted thereon for car rying a thread, with the attachment of the present invention applied thereto;

Fig. 3 is a sectional side elevation of a portion of the shuttle and showing the attachment partly in elevation and partly in central longitudinal section;

Fig. 4 is a horizontal sectional view taken on the line l l of Fig. 3.

As is well known in the art of weaving, a filling thread if permitted to be woven into the stock or material being produced, if

Serial N 0. 16,249.

such filling thread is imperfect by being deformed by reason of a-knot or slug, will result in a fabric having unsightly irregularities and of inferior quality. Therefore, to prevent such deformity in the thread from being woven into the fabric, an attachment of the character to belpresently described is attached'to a shuttle of anypreferred type, but preferably to the type of shuttle illustrated and described. in said patent granted to me. A descriptionof the construct'ionof the shuttle and bobbin carried thereby is thought to be unnecessary and will, there fore, be omitted.

The attachment of the present invention includes a support on casing 10, cylindrical for a portion of its length, as at 11, and attenuated, as at 12, to provide two fiat portions 13 spaced in parallelism. Arranged within the cylindrical portion 11 is a tensioning means 14, which consists of a part 15, a spring 16, and a fastening element 17. The part 15 is in the nature of a wire bent upon itself to provide spaced thread guides or loops 18 and angularly disposed extremities 19. The spring 16 is arranged between the extremities 19 and the element 17 which extends through the walls of the portion 11 and also takes into the shuttle 20, as shown in Fig. 3. A cutter or knife 21, having an angularly disposed cutting edge 22, and a thread controlling member 23, are carried by the casing 10 and are fastened between the port-ions 13 by suitable fasteners 24:. The member 23 has a section 25 which is angularly disposed with respect to the cutting edge 22, and has akerf 26 to provide a guide passage for the thread, and spaced portions 27 adapted to confront any deformity or enlargement of the thread as the thread moves from the bobbin 28 to the loops 18 of the tensioning means 14. It follows that because of the engagement of such enlargement or deformity of the thread, the thread will be held against movement at one point on the bobbin side of the tensioning means 14, and a pull exerted on the thread by the loom will place the thread under excessive tension and cause the means 14: to yield and as a consequence the thread will be severed by the cutting edge 22, as shown in Fig. 4. The attachment is held in place in the shuttle by a fastening element, such as the screw 29, which passes through the extremity 30 of the casing 10 and takes into the shuttle 20, as shown in Fig. 3. The severance of the thread, as will be understood, will prevent the faulty or imperfect part thereof from being incorporated into the fabric being woven and damage due to irregularities in the fabric will be obviated.

lVhat is claimed is:

1. For use in conjunction with a threadladen bobbin carried by a shuttle to cut the thread because of a fault or deformation of the thread, a device comprising a casing adapted tobe attached to the shuttle, thread tensioning means including spring-actuated guides, a knife juxtaposed with respect to said guides and carried by said casing, and a bifurcated member for controlling the movement of the thread in advance of its passage through said guides and capable of holding the thread against movement to cause the severance of the thread by said knife when a deformity of the thread engages the furcations of said bifurcated member.

2. The combination with a shuttle and a bobbin mounted thereon for carrying a thread, of an attachment removably carried by said shuttle adjacent one end of said bobbin, said attachment comprising a casing, thread tensioning means carried by said casing, said thread tensioning means including loops through which the thread passes; a cutter carried by said casing, and a bifurcated thread controlling member carried by said casing, the cutter being arranged between said tensioning means and said controlling means, the tensioning means being yieldable when a deformity on the thread engages said controlling member to allow a lead of the thread to be severed by said cutter.
